| Research Abstract |
Distribution of Fe among metal, silicates, and sulfide in protoplanetary disks could be a controlling factor of chemical composition of planetesimals and rocky planets. Kinetic parameters for metallic iron condensation and iron sulfide formation were obtained from reaction experiments under realistic protoplanetary disk conditions. The growth kinetics of forsterite, which may affect the condensation of metallic iron, was also experimentally determined.
